3RACING 3RB-681X-ZZ/2 Compact Double Metal Shield Bearings 1.5x4x2mm (2 pcs)  [3RB-681X-ZZ/2]

Replace Worn Bearings for Better Response

Fitting the 3RACING 3RB-681X-ZZ/2 double metal shield bearings is a simple way to restore smooth rotation to worn hubs or shafts. The 1.5 x 4 x 2 mm size is common in many small RC parts and helps reduce unnecessary drag.

Protection Against Track Debris

The double metal shields provide a barrier to dust and particulates while helping keep lubrication in place, so bearings maintain consistent rolling performance during hobby use.

Where These Bearings Work Best

They are suitable for small wheel hubs, pulleys and compact transmission locations where space is limited. Use them to improve efficiency and reduce replacement frequency in everyday RC use.
